Notepad Plugins Not Installing? Fixes That Work

Updated 14 November 2026 · Standard formula, shown below

If your Notepad++ plugins are not installing, the most common cause is a mismatch between the plugin version and your Notepad++ architecture (32-bit vs 64-bit), or the plugin being placed in the wrong folder. This article explains the exact causes and step-by-step fixes to get your plugins working again.

Background: Why Plugins Fail to Install

Notepad++ is a popular free text editor that supports plugins for added functionality, such as code linting, file comparison, and markdown preview. Plugins are distributed as DLL files that must be placed in the plugins subfolder of your Notepad++ installation directory. However, several factors can prevent them from loading:

Architecture mismatch: Notepad++ comes in both 32-bit and 64-bit versions. Plugins are compiled for one or the other. Installing a 64-bit plugin into a 32-bit Notepad++ (or vice versa) will cause the plugin to be ignored.
Wrong folder: Plugins must be placed in the correct plugins folder. On newer versions, each plugin should be in its own subfolder (e.g., plugins\MyPlugin\MyPlugin.dll).
Admin rights: If Notepad++ is installed in Program Files, you may need administrator permissions to write to the plugins folder.
Plugin Manager issues: The old Plugin Manager tool is no longer bundled with Notepad++ (since version 7.6). Users who try to install via Plugin Manager may find it missing or broken.

How Notepad++ Loads Plugins

When Notepad++ starts, it scans the plugins directory for DLL files and loads them. The exact behavior depends on the Notepad++ version:

Version 7.6 and later: The plugins folder is located in the same directory as the notepad++.exe file. Each plugin must be in its own subfolder, and the DLL must have the same name as the folder (e.g., plugins\ComparePlugin\ComparePlugin.dll).
Version 7.5 and earlier: Plugins were placed directly in the plugins folder (e.g., plugins\MyPlugin.dll).
Portable versions: The plugins folder is in the same directory as the executable, not in AppData.

If a plugin is not in the correct location or has the wrong name, Notepad++ will not load it, and you won’t see it in the Plugins menu.

Step-by-Step Fixes

Follow these steps in order to resolve most plugin installation issues:

Check your Notepad++ architecture: Go to ? (Help) → About Notepad++. Look for “32-bit” or “64-bit” in the version string. Download plugins that match that architecture.
Find the correct plugins folder: In Notepad++, go to Plugins → Open Plugins Folder. This opens the exact folder where plugins should be placed. If you don’t see this option, your version may be older or the folder is missing.
Place the plugin correctly: For Notepad++ 7.6+, create a subfolder inside the plugins folder with the same name as the DLL (without the .dll extension). Place the DLL inside that subfolder. For example, for MyPlugin.dll, create plugins\MyPlugin\ and put the DLL there.
Restart Notepad++: After adding the plugin, close and reopen Notepad++. If the plugin still doesn’t appear, try running Notepad++ as administrator (right-click → Run as administrator) to ensure it has permission to read the plugin.
Use the Plugin Manager (if available): If you have an older version of Notepad++ (pre-7.6), you can install the Plugin Manager from the official website. However, for newer versions, use the built-in Plugins Admin (available since version 7.6) via Plugins → Plugins Admin to install plugins directly from the repository.
Verify the DLL is not blocked: If you downloaded a plugin from the internet, right-click the DLL file, go to Properties, and check if there is an Unblock checkbox. If so, check it and click OK, then retry.

Common Mistakes and Misconceptions

Many users believe that plugins are installed by simply copying the DLL into the plugins folder, but that’s not always true for newer versions. Another common mistake is downloading a 32-bit plugin for a 64-bit Notepad++ (or vice versa). Also, some plugins require additional dependencies (like Python or specific runtimes) that must be installed separately.

Another misconception is that the Plugin Manager is still the only way to install plugins. In fact, Notepad++ 7.6+ includes a built-in Plugins Admin that connects to the official plugin repository. If you don’t see it, your version might be too old or the repository is temporarily unavailable.

Comparing 32-bit vs 64-bit Plugins

The architecture of Notepad++ determines which plugins will work. Here’s a quick comparison:

32-bit Notepad++: Runs on both 32-bit and 64-bit Windows. Plugins must be 32-bit. This is the most compatible choice if you rely on older plugins.
64-bit Notepad++: Runs only on 64-bit Windows. Plugins must be 64-bit. It can handle larger files and uses more RAM, but some older plugins are not available in 64-bit.

To check which version you have, go to Help → About Notepad++. The version string will include “(32-bit)” or “(64-bit)”.

Safety and Security Considerations

Plugins are code that runs with the same privileges as Notepad++. Only download plugins from trusted sources, such as the official Notepad++ plugin repository or the developer’s official website. Malicious plugins can compromise your system. Always scan downloaded DLL files with antivirus software before installing. Also, keep Notepad++ updated to the latest version to benefit from security fixes.

Alternatives to Notepad++ Plugins

If you’re having persistent issues with plugins, consider these alternatives:

Use built-in features: Notepad++ includes many features like macro recording, search with regex, and multi-editing that may cover your needs without plugins.
Switch to another editor: Visual Studio Code, Sublime Text, and Atom offer rich plugin ecosystems with easier installation via their built-in package managers.
Use portable Notepad++: A portable version can avoid permission issues and is easier to manage if you’re testing plugins.

Frequently Asked Questions

Why doesn’t my plugin show up in the Plugins menu?

Check that the plugin DLL is in the correct folder (as described above) and that the architecture matches. Also, ensure the plugin is not disabled in Plugins → Plugin Manager (if available) or Plugins Admin.

How do I install a plugin manually?

Download the plugin DLL, create a subfolder in the plugins folder with the same name as the DLL (without .dll), place the DLL inside, and restart Notepad++. For older versions, place the DLL directly in the plugins folder.

What is the Plugins Admin?

Plugins Admin is a built-in tool in Notepad++ 7.6+ that allows you to browse and install plugins from the official repository. Access it via Plugins → Plugins Admin.

Why does Notepad++ say “Plugin Manager is not available”?

This message appears when you try to use the old Plugin Manager on a newer version of Notepad++. Use Plugins Admin instead, or download the Plugin Manager separately if you’re on an older version.

Can I use 32-bit plugins on 64-bit Notepad++?

No. You must use plugins that match the architecture of your Notepad++ installation. Using a 32-bit plugin in a 64-bit Notepad++ will cause it to be ignored.

What should I do if a plugin crashes Notepad++?

Remove the plugin DLL from the plugins folder and restart Notepad++. If the issue persists, try reinstalling the plugin from a trusted source or check for updates.
